Abstract :

Quorum sensing is a central communication system and regulating system that lets bacteria coordinate group behaviors crucial for virulence, biofilm formation, motility, sporulation, toxin production, and resistance. There are two main types: acyl-homoserine lactones (AHLs) in Gram-negative bacteria and autoinducing peptides (AIPs) in Gram-positive bacteria. It means bacteria can use quorum sensing to make group decisions based on population density, which enhances coordination, efficiency, and adaptability and allows bacteria to act as a multicellular organism to perform tasks that are only effective in large groups. This article aimed to provide an overview of quorum sensing, types, and its mechanism.
